### Recap { #recap }

In summary, you declare **once** the types of parameters, body, etc. as function parameters.

You do that with standard modern Python types.

You don't have to learn a new syntax, the methods or classes of a specific library, etc.

Just standard **Python**.

For example, for an `int`:

```Python
item_id: int
```

or for a more complex `Item` model:

```Python
item: Item
```

			if testCase.inputMeta["etag"] != objInfo.ETag {
				t.Errorf("Test %d: %s: Calculated Md5 different from the actual one %s.", i+1, instanceType, objInfo.ETag)
			}
		}
	}

	// This causes quorum failure verify.
	os.RemoveAll(disks[len(disks)-1])

	// Validate the last test.
	testCase := struct {
		bucketName    string
		objName       string
		inputData     []byte

But it was created before there existed Python type hints. So, to define every <dfn title="the definition of how data should be formed">schema</dfn> you need to use specific utils and classes provided by Marshmallow.
